IMHO, the token ring is a superior protocol! It is deterministic, one could allocate bandwidth and priority to a given node, and many other benefits. The problem was marketing ant the greediness and over protection of IBM.
And look at the current Ethernet! Just a point-to-point, switched network, with a single point of failure.
Should also point out that the triumvirate of Digital Equipment Corp. (DEC)--remember those guys, Intel, and Xerox also had a hand in creating the 10-Mbit Ethernet standard that prevailed over the IBM token ring network and others. Funny how much history gets lost in time.
Replay available now: A handful of emerging network technologies are competing to be the preferred wide-area connection for the Internet of Things. All claim lower costs and power use than cellular but none have wide deployment yet. Listen in as proponents of leading contenders make their case to be the metro or national IoT network of the future. Rick Merritt, EE Times Silicon Valley Bureau Chief, moderators this discussion.
